2 Models of Urban Places Gideon Sjoberg explained the stages of urban development in The Preindustrial City: Past and Present (1960) Sjoberg said that all cities were a product of their societies and went through stages: Folk-preliterate Feudal Preindustrial Urban-industrial

3 Primate Cities Gideon Sjoberg was also the first to study the primate city. A nation’s leading city in size that serves as an expression of national culture. Not necessarily large Dominated by religious and govt. buildings Spacious with wealth near the center Less privileged near the edge or outside wall The leading city of a country. The city is disproportionately larger than the rest of the cities in the country. For example: London, UK Mexico City, Mexico Paris, France - the rank-size rule does not work for a country with a primate city

4 Primate Cities Positives? Negatives? Advantages of agglomeration
Large Market High-order services Enhanced flow of information Centralized Transportation Global Trade Unequal distribution of investments, resource development, wealth Transportation network prevents equal access to all areas Disproportionate effect of disaster Brain drain

5 Rank-Size Rule The larger the city-the fewer there are-
Model indicates that the population of a city or town in inversely proportional (the fraction) to its rank in the hierarchy If largest city is 12 million then 2nd largest is 6 m. (1/2) 3rd largest is 4 m. (1/3) 4th largest is 3 m. or (1/4) 10th largest is 1.2 million Rank-Size Rule does Not apply to primate Cities such as Paris, Mexico City and so forth Tokyo-Shinkuju District-Tokyo now has 28 m.& stretches 45 miles-the world’s largest urban center. Note the fraction bottom number gets larger-hence the reverse proportion. If time permits-Hand out Road Atlas and look at Iowa or another Great Plains state where the rank size rule holds true Rank-Size Rule: in a model urban hierarchy, the population of the city or town will be inversely proportional to its rank in the hierarchy. For example: largest city = 12 million 2nd largest = 6 million 3rd largest = 4 million 4th largest = 3 million

7 First Stage-Sail-Wagon Epoch (1790-1830)
John Borchert’s “American Metropolitan Evolution”-4 Stage model of evolution First Stage-Sail-Wagon Epoch ( ) slow, primitive overland and waterway transport-Boston, New York and Philadelphia were major cities oriented to European trade. Canal barge pulled by a horse in England

8 Second Stage-Iron Horse Epoch (1830-1870)
John Borchert’s “American Metropolitan Evolution-4 Stage model of evolution Second Stage-Iron Horse Epoch ( ) Diffusion of steam-powered railroads-coal mining-boomed, tracks laid coast to coast-manufacturing spread outward from New England hearth-by 1850 New York was primate city with Pittsburgh, Detroit & Chicago growing rapidly 1830s version of the steam locomotive

9 Third Stage-Steel-Rail Epoch (1870-1920)
coincided with the Industrial Revolution Steel industry in Chicago, Detroit & Pittsburgh Coal & iron ore supply areas-northern Appalachia and Lake Superior (Mesabi) Agglomeration in raw materials and market location due to railroad. Steel replaced iron rails-safer-more powerful locomotives-larger freight cars & even refrigerated cars added. 1923 steam locomotive on narrow gauge track in Colorado Mts.

10 Railroads between Stimulate economic growth: railroads connectivity/accessibility accelerated economic activity in cities Migration/labor force: population increased due to increased connectivity Corridors: cities increased in size along rail corridors due to increased connectivity Commercial zone: industrial land use area increased to accommodate rail yards, stations, warehouses, engine shops Cities declined: • Bypassed cities: some cities declined that were not connected to the RR network

11 How railroads affected the form of cities
CBD growth: central business district emerged and expanded Urban pattern: star patterns or hub-and-spoke patterns, streetcar suburbs, wider roads Land values: real estate around passenger stations became more valuable and popular; railroads created socio-economic divisions

12 Fourth Stage-Auto-Air-Amenity Epoch (1920-1970)
Gasoline-powered internal combustion engines-truck based regional and metropolitan distribution of goods; increased automation of blue-collar jobs; shift to white-collar jobs; highways, expressways and jet aircraft made travel faster & cheaper; amenities of suburbs, Sunbelt; New activities responded less to cost-distance factors Freeway interchange near Los Angeles-Pasadena to Santa Monica interchange Schiphol airport outside of Amsterdam, Netherlands

13 How highways affected U.S Urban Areas
Relocation of economic activities: services, offices, retailing centers, transportation hubs, light industry and warehousing to highway interchange areas Suburbanization: larger suburban labor force could independently access downtowns by car without living there; contributed to decline or depopulation of city centers Land use change: sprawl, suburban area expands as highways radiated out of city; more land area to automotive uses (e.g., parking lots, more lanes, eminent domain); divides city and creates socioeconomic divisions Increased economic connectivity Edge cities Environment: Some Cities decline due to by passes (Route 66)

14 Fifth Stage?- (1970-Now) decline of Rust belt continues;
high tech. will stimulate an even greater dispersal of city populations; telecommuting, working from home, globalization and outsourcing change the way we work Zenith plant in Reynosa, Mexico

15 Modern Urbanization Southwest Asia-North Africa-great variety of urbanization. Much of Middle East, esp. Arabian Peninsula are highly urbanized due to nucleation of the oil industry. Jordan an exception-no oil wealth-but urban due to long tradition Southern Arabia is oil poor and rural Contrast-oil rich Libya is urban, oil poor Afghanistan is rural

16 Most nations in South Asia are under 30% urban India-26% Pakistan-28%
Modern Urbanization South Asia-low in urbanization, despite huge cities like Mumbai and Calcutta Most nations in South Asia are under 30% urban India-26% Pakistan-28% Bangladesh-16% Subsistence farming dominates life here Calcutta street scene

17 Southeast Asia- Singapore is the only 100% urban state
Modern Urbanization Southeast Asia- Singapore is the only 100% urban state Brunei & Malaysia are the only other nations with over 50% urban Indonesia-31% Myanmar-25% Vietnam-20% Thailand-19% Subsistence farming dominates life here Indonesian rice paddies on terraces on the island of Bali

18 Only Japan, South Korea and Taiwan are highly urbanized in East Asia
Modern Urbanization East Asia- Averages 36% Only Japan, South Korea and Taiwan are highly urbanized in East Asia China below-25% Yet Shanghai & Beijing Have 25 million between Them, however most of China’s 1.2 m. are rural Hong Kong street scene

19 Problems in Urban America
200 years ago only 5% of world was urbanized Today about 50% is urban Germany, Spain & Belgium are over 90% urban World wide urban problems are: pollution poor sanitation drugs and crime congestion and noise substandard housing & slums

20 Problems in Urban America
With urban sprawl and expanding suburbs-inner city shrinks CBD is often reduced to serving just the inner metro area As basic sector jobs leave-large cities have shifted to service industries Loss of tax base as businesses, industries and services leave Urban decay results Unable to fund adequate schools, crime prevention programs, public housing and services-a downward spiral begins. Row houses abandoned in North Philadelphia

21 Problems in Urban America
New York City a good example: 3 million people plus uncounted illegals crowd into 75 to 100 year old apartment buildings Many buildings are worn out, rat & roach infested with high crime rates, vandalism and cases of spouse & child abuse Yet despite the problems there is a sense of community that may be lost if the neighborhood is torn down

22 Making Cities in the Global Periphery and Semiperiphery
sharp contrast between rich and poor - Often lack zoning laws or enforcement of zoning laws

23 The Ibero-American City
Latin American cities are growing rapidly-1950= 41% urban, % urban CBD dominates the center with 2 main divisions-traditional market and modern high rises A commercial spine and axis of business is surrounded by elite residential housing Griffin-Ford model

24 The Ibero-American City
The spine is an extension of the CBD with offices, shops, high class housing, restaurants, theaters, & parks Zone of Maturity-Middle class housing 2nd best Zone of In Situ Accretion-high pop. Density of modest housing Periphery-Periferico-high density shanty towns of extreme poverty and no services (favelas) Mexico City-Paseo de Reforma a major boulevard from the CBD Favela of Rio de Janeiro on a hillside Unlike America cities-the poverty areas are concentrated in squatter settlements on the outskirts of town-the poorest live the farthest from the CBD

25 The African City African cities often have 3 CBDs=Colonial, Traditional and Periodic Market Zone Sub-Saharan Africa is the least urbanized area of the world, but the most rapidly urbanizing No large cities to match Cairo-Kinshasa, Nairobi, Harare, Dakar, Abidjan were established by Europeans de Blij model

26 The African City No large cities to match Cairo-Kinshasa, Nairobi, Harare, Dakar, Abidjan were established by Europeans South African cities-Johannesburg, Cape Town & Durbin are western cities with elements of European and American models-high rise CBDs and sprawling suburbs Nairobi, Kenya

27 The Southeast Asian City
SE Asia-rapid growth of population & cities % urban, 1990s-29% urban Most growth in coastal cities like Ho Chi Minh City (Saigon) Old colonial port zone surrounds the commercial district Unlike Western cities-no formal business zone, but separate clusters McGee model

28 The Southeast Asian City
Singapore-Container Port Malaysia-Kuala Lumpur-Petronas Towers-highest building in the world if you count the antenna towers Malaysia is building a new capital city 25 miles south of Kuala Lumpur
